set_operating_conditions -grade Q-Grade set_operating_conditions -grade Extended UltraScale架构的FPGA芯片的名称已经包含了温度等级信息,因此再运行SSN分析时会自动调用。使用“report_operating_conditions -grade”可以查看温度等级。
set_operating_conditions -process maximum Junction Temperature: Leakage current increases exponentially with Junction Temperature which results in higher Static Power. Junction Temperature depends on various factors: the total power of the device, the cooling system, board selection and ambience. ...
这通常通过设置适当的时序约束来实现,例如使用set_operating_conditions命令来定义不同的PVT条件。tcl # 示例:设置典型工艺角的时序约束 set_operating_conditions -name typical -library {typical_lib} -max_delay {max_delay_file} -min_delay {min_delay_file} 注意:这里的{typical_lib}、{max_delay_file}...
因此不需要等效的TEMPERATURE约束。实现工具在时序驱动算法中不使用'set_operating_conditions'。

(Xilinx Answer 64443)set_operating_conditions does not change project part when Vccint value is set outside the range of the current device Vivado exits unexpectedly when the GUI is launched through a remote access and using an Asian operating system ...
Including operating conditions such as voltage settings, power and current budgets, and operating environment details. Switching activity rates for individual nets and pins、block RAMs, DSPs, and transceivers and global set and reset signals.
提示:在设计进程中,您可以使用 set_operating_conditions -design_power_budget Tcl 命令将设计的总功耗与功耗预算进行比较.如果超出功耗预算,最简便的设计功耗修正方式就是早期干预. 利用 Xilinx Power Estimator(XPE) 进行最差情况功耗分析 赛灵思建议针对最坏情况的功耗设计主板.欲知详情,请参阅 《Vivado Design ...
UCF约束默认不对异步时钟间路径进行时序分析,而XDC约束默认所有时钟是相关的,会分析所有路径,可以通过设置时钟组(set_clock_groups)取消时钟间的相关性。 下面介绍一下在Vivado中添加XDC文件以及加入约束命令的方法:首先在Pro 7、ject Manager中展开Constraints类,选择Add Sources即可添加或者新建XDC约束文件,如图2所示。
For Linux operating systems, licensing environment variables cannot be set using the Vivado License Manager (VLM). The environment variable fields are read only, so they are grayed out and there are no Set buttons. The environment variable must be set using the appropriate OS shell and commands...
